Subject:   ODROID C1+ doesn't finish booting on 11-CURRENT after r301062

Hi,

My ODROID C1+ gets stuck during boot starting with r301062
(still gets stuck with r301778).

Sometimes there are continuous prints of
"mmcsd0: Error indicated: 1 Timeout".
When there are no mmcsd timeouts, it still doesn't get to
the login prompt with last print being the NIC bringup.

Adding the bellow print code to gic_bind() mask loop,
I see arm_gic_map[cpu] is 0 when setting one of the IRQs.

for (mask = 0, cpu = 0; cpu < end; cpu++)
  if (CPU_ISSET(cpu, cpus)) {
    mask |= arm_gic_map[cpu];
    if (arm_gic_map[cpu] != 1 << cpu)
       device_printf(sc->gic_dev,
         "irq = %u, cpu = %u, arm_gic_map[cpu] = 0x%08x\n",
         irq, cpu, arm_gic_map[cpu]);
  }

# dmesg | grep -B1 arm_gic_map
Release APs
gic0: irq = 32, cpu = 1, arm_gic_map[cpu] = 0x00000000

# dmesg | grep -B1 arm_gic_map
Release APs
gic0: irq = 35, cpu = 2, arm_gic_map[cpu] = 0x00000000


If I add prints to the end of gic_bind() the board boots fine.
(Probably because of the delay added by the prints)

Example:
device_printf(sc->gic_dev, "irq = %u, mask = 0x%08x\n", irq, mask);
return (0);

# dmesg | grep -e "gic0: pn" -e "gic0: irq" -e "Release APs"
gic0: pn 0x390, arch 0x1, rev 0x1, implementer 0x43b irqs 256
gic0: irq = 32, mask = 0x00000001
gic0: irq = 42, mask = 0x00000001
gic0: irq = 122, mask = 0x00000001
gic0: irq = 58, mask = 0x00000001
gic0: irq = 107, mask = 0x00000001
gic0: irq = 125, mask = 0x00000001
gic0: irq = 60, mask = 0x00000001
gic0: irq = 110, mask = 0x00000001
gic0: irq = 62, mask = 0x00000001
gic0: irq = 63, mask = 0x00000001
gic0: irq = 40, mask = 0x00000001
gic0: irq = 35, mask = 0x00000001
Release APs
gic0: irq = 32, mask = 0x00000002
gic0: irq = 35, mask = 0x00000004
gic0: irq = 40, mask = 0x00000008
gic0: irq = 42, mask = 0x00000001
gic0: irq = 58, mask = 0x00000002
gic0: irq = 60, mask = 0x00000004
gic0: irq = 62, mask = 0x00000008
gic0: irq = 63, mask = 0x00000001
gic0: irq = 107, mask = 0x00000002
gic0: irq = 110, mask = 0x00000004
gic0: irq = 122, mask = 0x00000008
gic0: irq = 125, mask = 0x00000001


Thanks,
